Jeff Hao436183f2016-01-12 16:36:50 -08001904 // 3. We create the oat files. Originally this was just our own proprietary

Vladimir Markof4da6752014-08-01 19:04:18 +01001907 // can prepare the ELF headers and we then know the ELF memory segment

1915 // memory mapped so we could predict where their contents were based
1916 // on the file size. Now that they are ELF files, we need to inspect
